Concept Evaluation Methodology for Extraterrestrial Habitats

Abstract

The paper examines and compares structural concepts considered for use as habitats for lunar and Martian outposts. An evaluation methodology that allows numeric rating of concepts was previously developed and is upgraded herein. The methodology defines a number of important characteristics on which concepts are to be judged. In addition, weighting factors are assigned for the various characteristics considered in the evaluation system. These factors are presented as variables that depend on mission goals and timing aspects. An example evaluation is made for a specific scenario utilizing the developed methodology. The overall purpose of this work is not to provide an absolute rating, but rather to identify strengths and weaknesses of concepts. This approach should be invaluable in the development and selection of structural concepts for extraterrestrial habitats.
